Write the ideal gas equation. What is the basis of the absolute temperature scale?

(N/A) The ideal gas equation is given by $PV = nRT$,where $P$ is the pressure,$V$ is the volume,$n$ is the number of moles,$R$ is the universal gas constant,and $T$ is the absolute temperature.
The basis of the absolute temperature scale (also known as the Kelvin scale) is the absolute zero temperature,which is $-273.15 \ ^{\circ}C$. At this temperature,the pressure of an ideal gas becomes zero,as shown in the graph where the pressure-temperature line extrapolates to zero pressure at $-273.15 \ ^{\circ}C$.
